At the top of the script:

pawn Код:

new PlayerHasVehicle[MAX_PLAYERS]; // Global variable for all the players.

When the player connects:

pawn Код:

public OnPlayerConnect(playerid)
{
    PlayerHasVehicle[playerid] = -1; // The default vehicle ID (user defined) if he hasn't got a vehicle.
    return 1;
}

The new /v command:

pawn Код:
